Obama violated them straightaway. He imposed new sanctions on Iranian, Asian and European companies. He did so on individuals. He did it unilaterally by executive order.

Asking Congress to hold off on more rings hollow. He could have normalized relations straightaway in office if he wanted.

His policies are polar opposite. They've been so all along. Is this time different? His record suggests otherwise.

Iran has no guarantees. It has reason for concern. It's been betrayed many times before. It's hard imagining changed US policy. It remains hardline. It threatens world peace.

Esmayeel Kosari is an Iranian parliamentarian. He's a National Security and Foreign Policy Commission member. He expressed concern, saying:

"Iran's nuclear activities have turned into a pretext in the hands of the western countries in recent years, and each time they make our country's (nuclear) case more complicated under such pretexts (of) transparency and confidence-building."

"Convincing public opinion of the peaceful nature of Iran's nuclear activities will certainly be a great failure for the Americans, and therefore, they continuously rock the boat in order not to allow this to happen," he said.

Deputy Foreign Minister Majid Takht-Tavanchi said Israeli officials and their US supporters deplore rapprochement with Iran.

"The Zionist lobby sustained a defeat in the recent agreement in Geneva," he said. It "improved Iran's regional and international position and (its) regional power was recognized."
